RECENTLY I have examined several samples of cast plasticized secondary cellulose acetate sheet material under the microscope. With crossed nicols a uniform yellow polarization colour was shown, indicating a considerable amount of orientation. Taking the casting flow-lines, parallel to the `selvedge' ...

A melt extrusion process for producing a low density open cell filtering element for an aerosol such as tobacco smoke from plasticized cellulose acetate. A mixture of cellulose acetate, plasticized, a volatile liquid blowing agent which is at least a partial solvent for the cellulose acetate and ...
Three potential anion receptors (L1-L3) with varying terminal substituent have been designed, out of which, only with receptor L1, successful crystallization with acetate anion was achieved. For the other two receptors (L2 and L3) crystallisation attempts with anions was unsuccessful; the reasons ha...
In polymethylmethacrylate and cellulose acetate the kinetics of triplet cyclohexadienone carbenes decay by 77135 K including a hydrogen atom transfer from CH bonds of macromolecules with the radical pair formation was examined. The kinetics of this process reflects the influence of peculiarities on a ...
After partial degradation of CL by cellulase, the UV elution curve of CL acetate shifted to the low-molecular-mass region in a similar fashion as its RI elution curve. These results indicate that the lignin in CL (CL lignin) is chemically bonded to cellulose. On the other hand, half of ...
A total of 16 signals can be identified belonging to the K15 PS in panel (B); the ‘*’ marks indicate narrow trace signals from K15 decomposition (acetate and glycerol). Full size image The presence of only two resonances of similar intensities in the anomeric region of the 13C -NMR ...

Materials rich in lignocellulose, such as straw, are abundant, cheap and highly interesting for biogas production. However, the complex structure of lignocellulose is difficult for microbial cellulolytic enzymes to access, limiting degradation. The rate
